Comments on: U.S. Energy Secretary Steven Chu: “Global Warming Is the Greatest Challenge Facing Science” http://dirt.asla.org/2009/06/22/u-s-energy-secretary-stephen-chu-global-warming-is-the-greatest-challenge-facing-science/ Connecting the Built & Natural Environments Thu, 11 Mar 2010 20:39:08 +0000 http://wordpress.com/ hourly 1 By: Tom Fortner http://dirt.asla.org/2009/06/22/u-s-energy-secretary-stephen-chu-global-warming-is-the-greatest-challenge-facing-science/#comment-736 Tom Fortner Mon, 05 Oct 2009 18:35:55 +0000 http://dirt.asla.org/?p=2246#comment-736 I read Dan Pangburn's article at www.middlebury.net/op-ed/pangburn.html, the short entry above, and hundreds of climate change articles including the one referenced by him above. To state it simply, scientists overwhelmingly agree that the data show there is a very strong correlation coefficient between increasing CO2 levels and higher average climate temperatures over time. Clearly, with something as complex as global climate, for relatively short periods of time, CO2 levels may increase while temperatures fall, but looking at the trends over long periods of time and even most short ones (e.g. since the Industrial Revolution), it is obvious even to those of us who are not trained climate scientists that increasing levels of CO2 and higher temperatures go hand in hand.

That error has been propagated throughout the Climate Science community and has contributed substantially to the Global Warming Mistake. Those who understand ALL of the relevant science know that added atmospheric carbon dioxide does not significantly increase average global temperature. The issue exists because Climate Scientists appear to be unaware of the science that disproves AGW (it is not in their curriculum). Find out more from the pdfs that can be accessed at http://climaterealists.com/index.php?tid=145&linkbox=true . Cost effective improvement in efficiency is just common sense and doesn't need any government regulation. James Hansen misapplied ‘feedback’ in his 1984 paper.
